The trends and spreads of tropospheric and stratospheric temperature are
discussed in terms of three groups of datasets in 1979–2008. These datasets
include (a) three satellite observations of Microwave Sounding Units (MSU)
measurements, (b) five radiosonde observations and (c) five reanalysis
products. The equivalent tropospheric and stratospheric temperature from
radiosonde and reanalyses are calculated based on the vertical weighting
function of the MSU channel 2 (CH2) and channel 4 (CH4) measurements,
respectively. The results show that both cooling in the stratosphere and
warming in troposphere significantly depends on the datasets and latitudes.
